The present invention relates to dough coilf The machine illustrated in the drawing is ing machinesan'd particularly to a 'cornicle provided with fiverollers, four of which are winding machine which in contrastwith the grouped around the principal roller 2. In machines of this characterhitherto known this manner the sheeting roller together 5 entirely dispenses with the use of 'bandsffor. with thesheeting roller 1, and the roller 2 guiding and shaping the dough. Such bands serye', for spreading the dough, and for conhave a series of considerable disadvantages. v'ey'ing the rolled sheet of dough to the coil- The bands'easily stretch during the operation ting or winding rollers 3 and 4; The mountof the machine as they absorb moisture, they ing of the rollers l and 5, which serve to roll Wear rapidly, and tear,whereby the operation 7 out the'douglnis adjustable in the direction 60 of the machine is disturbed, Suggestions hB'a r W a preferably in such a manner have already been madeto effect the winding that the roller 5 only comes into operation for itself by nieans'of three rollers of which one operatingupon large pieces of'dough. Both is yieldingly mounted, but in this connection these rollers rotate in the opposite direction 1 noconsiderationlwas paid to the fact that to the pr ncipal roller 2. 3

the pressure of the rollers must be suitably The w nd ng of the rolled sheet of dough reducedas the winding'of the cornic leli 1S effected ln a triangular'space formed becreases its size. tween the rollers 2, 3 and 4' which all rotate According to the present invention a varia- :in'the same direction; 'The'roller is adjusttion of thewinding pressure, as thes'ize of able'andis'for example mounted in levers b 70 the cornicle increases, is eifected in a; simple Wlllch Can fr ely k 011 e Shaft 0f he fnain manner by the use of a yielding winding roller 2.

them is enlarged more and more by the yieldbecome so large that the completely wound cornicle .e i falls. out automatically. The os--' cillatory roller4 then immediately; returns to its initial position in which ittouches the roller 3.

The machine maybe driven by a belt pulley mounted on one ojffthe shafts of the: rollers, whilst the otherrollers are driven by interengaging gears or the like. i I
